Abstract
Sleep deprivation and starvation both produce increased waking in Drosophila during the period of treatment, but both produced a different post-treatment response. After flies undergo sleep deprivation an increase in sleep is observed compared to sleep baseline. However, in flies that experience starvation conditions sleep tends to return to the pretreatment level. We will use mathematical modeling of sleep to determine any subtle differences in sleep patterns pre and post treatment. Males and females of three different genotypes will be used. These mutant genotypes include tim 01, cyc 01, which lack a circadian rhythm. The wild type, CS Skeath, will be used as a control. These flies will be placed in complete darkness for 48 hours and then are sleep deprived by either sleep deprivation or starvation for 12 hours. Post treatment sleep is measured for 48 hours, and analysis is done to detect a difference.
